## `websocket` を作成する

**FastAPI** アプリケーションで、`websocket` を作成します。

```Python hl_lines="1  46-47"
{!../../docs_src/websockets/tutorial001.py!}
```

/// note | "技術詳細"

`from starlette.websockets import WebSocket` を使用しても構いません.

**FastAPI** は開発者の利便性のために、同じ `WebSocket` を提供します。しかし、こちらはStarletteから直接提供されるものです。
